This is a new issue by the way. I cannot remember what version exactly, but previously I was using a version of around 07-07 and that was working for me fine. I only noticed this error as my CI which uses whatever latest nightly got this error for the doc test. Trying it with latest nightly myself locally gives me 100% this failure as well, but only for cargo doc. All other cargo commands work fine.

E.g. cargo run, cargo test, cargo clippy, etc etc... these all work fine.

GlenDC · 2023-07-13T21:06:12Z

Is there something you or anyone need more from me on this one by the way?

GlenDC · 2023-07-14T13:53:01Z

FYI, for now I pinned my toolchain to nightly-2023-07-08 and that makes it work for my dev machine, as well as my CI. So I am not blocked on this. If you do need me for more input or information, do let me know. And thank you for everything.

compiler-errors · 2023-07-14T13:56:48Z

No, I'll take a look at this today and hopefully have a fix up soon. Thanks, @GlenDC.

spastorino · 2023-07-14T14:11:36Z

We're accessing hir for RPITITs in this case in ...

    // FIXME(@lcnr): Remove this function.
    pub fn get_attrs_unchecked(self, did: DefId) -> &'tcx [ast::Attribute] {
        if let Some(did) = did.as_local() {
            self.hir().attrs(self.hir().local_def_id_to_hir_id(did))
        } else {
            self.item_attrs(did)
        }
    }

Likely we want a check for self.is_impl_trait_in_trait(did) to avoid doing so.

GlenDC · 2023-07-17T22:31:49Z

This might also be the reason why docs are for now failing at docs.rs.I guess?

https://docs.rs/crate/tower-async/latest

GlenDC · 2023-07-18T08:13:31Z

This is the url to the build log btw: https://docs.rs/crate/tower-async/0.1.0/builds/863682 (you can also access it from the linked docs.rs crate doc page). Too bad I cannot select the toolchain with https://docs.rs/about/metadata that would fix it for that use case as well.

GlenDC · 2023-07-27T16:32:41Z

Can I help with fixing this issue? If someone can mentor me I do not mind picking it up?

compiler-errors · 2023-07-27T16:34:08Z

Sorry, I'm working on it. I was experimenting with a bit more thorough fix, but that fell through the cracks since I was traveling the past few weeks.

GlenDC · 2023-07-27T17:09:02Z

Ah yes, no worries. No pressure. In that case I’ll wait patiently. Do let me know if I can be of any more meaning now or later, as I’m pretty invested in these functionalities.

compiler-errors · 2023-09-07T02:41:16Z

This issue got fixed, right? I can't reproduce it (using plabayo/tower-async#bd868b123eeb4fc65ea066fb107e3e41c306b4b3 from your repo).

compiler-errors · 2023-09-07T02:42:38Z

(closing, please reopen if it's in-fact not fixed. I think @fmease inadvertently fixed this in #113956).

GlenDC · 2023-09-07T11:24:52Z

Can the docs.rs version of https://docs.rs/crate/tower-async/0.1.1 be recompile for me? Or do I need to request that as a separate issue somewhere else @compiler-errors ?

fmease · 2023-09-07T11:32:32Z

I'm not on the docs.rs team (only on the rustdoc-contributors team) and therefore don't know their procedures. However, after having read https://docs.rs/about/builds#failures-and-rebuilds it seems to me that you can request a rebuild after a bug in ~~docs.rs~~ rustdoc has been fixed … by opening an issue in rust-lang/docs.rs, maybe. You might want to try that :)

GlenDC · 2023-09-07T13:07:29Z

Thanks I have opened an issue in the right repo, rust-lang/docs.rs#2215.
